CWE-89Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection')

Description

Common consequences· 5

• Confidentiality / Integrity / Availability — Execute Unauthorized Code or Commands
  Adversaries could execute system commands, typically by changing the SQL statement to redirect output to a file that can then be executed.
• Confidentiality — Read Application Data
  Since SQL databases generally hold sensitive data, loss of confidentiality is a frequent problem with SQL injection vulnerabilities.
• Authentication — Gain Privileges or Assume Identity, Bypass Protection Mechanism
  If poor SQL commands are used to check user names and passwords or perform other kinds of authentication, it may be possible to connect to the product as another user with no previous knowledge of the password.
• Access Control — Bypass Protection Mechanism
  If authorization information is held in a SQL database, it may be possible to change this information through the successful exploitation of a SQL injection vulnerability.
• Integrity — Modify Application Data
  Just as it may be possible to read sensitive information, it is also possible to modify or even delete this information with a SQL injection attack.

• [Architecture and Design]
• [Architecture and Design, Operation]
• [Architecture and Design]For any security checks that are performed on the client side, ensure that these checks are duplicated on the server side, in order to avoid CWE-602. Attackers can bypass the client-side checks by modifying values after the checks have been performed, or by changing the client to remove the client-side checks entirely. Then, these modified values would be submitted to the server.
